However, the method of installing a light shelf or louver has a problem that it takes time and cost to install the light shelf or louver. In particular, when a light shelf or a louver is installed outdoors in a renovation work for a middle-rise building or a high-rise building, a large-scale exterior work is required.
On the other hand, the method of applying a photorefractive film to a window surface does not require large-scale exterior construction, but if the photorefractive film is applied at a position lower than the resident's line of view, the daylight that refracts toward the ceiling is refracted. Since it hits a resident, there is a problem that the resident feels dazzling. For this reason, it is conceivable that the photorefractive film is not attached to a position lower than the line of sight. However, in this way, there is a problem that daylight directly enters from a portion where the photorefractive film is not attached.

  The present invention has been made in view of the above-described problems, and can easily improve the indoor light environment while efficiently introducing daylight from a window and reducing illumination energy.
